Homodimerization of the membrane-bound collagenase MT1-MMP [membrane-type 1 MMP (matrix metalloproteinase)] is crucial for its collagenolytic activity. However, it is not clear whether this dimerization is regulated during cellular invasion into three-dimensional collagen matrices. To address this question, we established a fluorescence resonance energy transfer system to detect MT1-MMP dimerization and analysed the process in cells invading through three-dimensional collagen. Our data indica...Expand abstract
